Other forms of plague

This code signifies atypical presentations of plague that do not fit the criteria for bubonic, pneumonic, or septicemic forms. It encompasses less common manifestations of Yersinia pestis infection, such as pharyngeal plague, meningeal plague, or cutaneous plague. These forms often arise from direct inoculation or dissemination from other sites.

Use this code when documentation specifies a confirmed plague infection that is not clearly bubonic, pneumonic, or septicemic. This includes cases where the primary site of infection is the pharynx, meninges, or skin, without evidence of widespread systemic involvement typical of the more common forms. Supporting documentation should clearly identify the specific atypical presentation.

• Do not use this code if the documentation clearly indicates bubonic, pneumonic, or septicemic plague; use the specific code for those forms.
• Ensure the medical record explicitly states "other forms of plague" or details a specific atypical presentation.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter.
